First post and hoping to learn from the BP community.I currently own a rental property, and am interested in either building a DADU or exploring the possibility of subdivision.

Overall, there are a ton of really helpful suggestions in the replies here so I think you should definetley weigh some options in terms of if your goal is to keep the tenants or have the units be up to market rent. 

I am particularly interested in areas which I can either start earning right away as short term or long term rentals - Miami area or Bay area sounds like a good option for me.

Looking for long term financing options.

Some of the core topics we hope to explore in our BiggerPockets profile include:- How our military experience has prepared us for the challenges of real estate investing- The process of getting started, from investment knowledge, to understanding different roles and titles used by real estate investors- The specific goals and milestones we've set for ourselves as we navigate this new field- The surprises, setbacks, and moments we encounter as we learn the ropes of real estate investingBy sharing our journey, we aim to provide a helpful resource for other newcomers looking to get started in real estate.

You would need to consult with a (local) lender to see what is available to you for that property, but I am assuming 20-30%.You would likely have 2 options with that property - 3 2 bedroom unit listings, or 1 6 bedroom listing. 

You may want to consider promo rates on an equity line as well and if they offer you the option to convert any part of the equity line into a fixed loan.

I wrote down all these tools and will explore what they are for today! 

Open to any and all options and appreciate the advice/input from qualified, experienced, investors and professionals.Thanks in advance!
